About the role

We are looking for a Computer Vision and Machine Learning (CV/ML) Engineer to develop and deploy intelligent perception systems for our autonomous drone-in-a-box platform. You will work on challenging real-world computer vision problems, from real-time object detection and tracking on embedded devices to advanced scene understanding and cloud-based inference. As part of a small, technical team, you will own solutions across our software stack, taking algorithms and models from prototype to deployment. This position is for an on-site employee for our Zurich office. Responsibilities • Design and develop a wide variety of computer vision and machine learning features for real-time unmanned aerial vehicle (UAV) applications • Train, fine-tune and evaluate deep learning models for tasks such as object detection, instance segmentation, image retrieval/reidentification • Optimize algorithms and models for edge devices (NVIDIA Jetson and Qualcomm Dragonwing), and integrate them into our image and video processing pipelines • Monitor ML model performance in real-world deployments and set up workflows for continuous improvement (data collection, curation, labeling, retraining, evaluation) • Evaluate and integrate large/vision language models for scene understanding, situational awareness, and hazard analysis, including prompt design, performance benchmarking, and production deployment Qualifications • Degree in Computer Science, Robotics Engineering, Electrical Engineering, or a related field (or equivalent practical experience) • Solid understanding of computer vision and machine learning fundamentals • Strong programming skills in Python and C++, with experience developing production-grade software that powers CV/ML systems • Experience with PyTorch or TensorFlow, ONNX, TensorRT, CUDA • Experience with end-to-end model development: from dataset curation, labeling strategies, active learning workflows to deployment and optimization for edge devices • Excellent oral and written skills in English • Work permit in Switzerland required Bonus Points • Good understanding of 3D vision and robotics perception, along with hands-on experience with OpenCV and ROS/ROS2, is a strong plus • Experience with NVIDIA Jetson and Qualcomm edge devices, and their CV/ML SDKs • Experience with transformers, large/vision language models and prompt design for perception tasks • Experience with GStreamer pipelines and custom plugin development • Experience with AI-assisted development tools and coding agents (e.g., Claude Code, Codex, Cursor) in a professional setup to accelerate implementation, debugging, testing, and review 100% · On-site
